Researchers improve safety of lead-based perovskite solar cells

Golden CO (SPX) Feb 27, 2020

Researchers at the National Renewable Energy Laboratory (NREL) and Northern Illinois University (NIU) have developed a technique to sequester the lead used to make perovskite solar cells, a highly efficient emerging photovoltaic technology. The light-absorbing layer in a perovskite solar cell contains a minute amount of lead. The presence of this toxic material in the developing technology
